What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe intracellular symbiont Wolbachia, particularly the wAlbB strain, is a promising biocontrol agent against mosquito-borne diseases. Although Wolbachia infection is known to perturb host metabolism, the underlying mechanisms, especially those related to lipid metabolism, remain poorly understood.
methodsWe performed an integrated multi-level analysis of the Aedes aegypti fat body in uninfected and wAlbB-infected mosquitoes, combining histology, biochemistry, untargeted liquid chromatography-mass spectrometry (LC-MS) lipidomics, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways enrichment analysis, reverse transcription quantitative PCR of key metabolic genes, and quantification of acetyl-coenzyme A (acetyl-CoA) and reduced nicotinamide adenine dinucleotide (NADH) levels.
resultswAlbB infection increased fat body wet weight and thickness, accompanied by accumulation of triglyceride and of lipid droplets. Lipidomic analysis further revealed extensive lipidome remodeling, with elevated free fatty acid, diglyceride, and triglyceride, but broad depletion of glycerophospholipids, particularly cardiolipin. These changes were supported by transcriptional alterations: upregulation of fatty acid synthase 1 and glycerol-3-phosphate acyltransferase 1, and downregulation of adipose triglyceride lipase and carnitine palmitoyltransferase 1. Cardiolipin depletion correlated with downregulation of genes involved in its synthesis and remodeling, including phosphatidylglycerophosphate synthase and calcium-independent phospholipase A2γ. These lipid changes were also associated with accumulation of acetyl-CoA and NADH.
conclusionsOur findings suggest that wAlbB infection is associated with extensive lipid metabolic remodeling in the Aedes aegypti fat body, characterized by accumulation of neutral lipids and cardiolipin depletion, accompanied by transcriptional remodeling of key metabolic enzymes. This study establishes the fat body as a primary tissue-level hub for Wolbachia-associated lipid remodeling and provides a foundational framework for future mechanistic investigations into host-symbiont metabolic interactions.
